I'd love to see that email. I received no such email and no instructions about how not to be migrated.
My plan renewed on 2025-05-04. On 2025-04-04 I received an email w/ the subject line "Upcoming Microsoft 365 price change". This email stated:
> Thank you for being a valued Microsoft 365 subscriber. To reflect the value we’ve added over the past decade, address rising costs, and enable us to continue delivering new innovations, we’re increasing the price of your subscription.
> Effective February 14, 2025, the price for Microsoft 365 Family subscriptions will increase from USD 99.99* per year to USD 129.99* per year.

I don't have an archive of the page as it appeared on 2025-04-04. Right now it makes mention of the Microsoft 365 Family "Classic" plan at the old $99 rate.
My recollection is that the page, as of 2025-04-04, also made no mention of the "Classic" plan, and offered no instructions re: not being "upgraded".
Months before the pricing change went into effect Microsoft sent me a detailed email about how to stay on the old pricing plan.
I don't appreciate being auto migrated, but they did originally provide instructions on how to not be migrated.
